:MMEMory:MSIS Subsystem
The Mass MEMory “Mass Storage IS” subsystem contains commands for selecting a mass storage device that is used by all of the MMEMory commands.
 
Save Location
:MMEMory:MSIS
Description
Sets the instrument’s internal memory or the USB Flash drive as the save location for all subsequently saved files. This command also determines the destination location for copied files. For example, selecting internal memory as the current save location will set the USB Flash drive as the destination for copied files, and vice-versa.
Note that the save location specified here applies to remote operation. It is independent of and can be different from the save location set via the instrument front panel. The query form of this command returns the save location setting for remote operation, not the front panel setting.
Commands to load, store (save), or copy data will fail if the intended location is not available. This is the case if the USB drive is selected and no USB device is plugged into the instrument.
Before setting the save location, send the :SYSTem:MSIS? USB command to query the ready state of the USB Flash drive.

Copy From Current Location To Destination
:MMEMory:MSIS:COPY
Description
Copies all files and folders from the current save location to the destination. File hierarchy is maintained. When copying to USB, all data is placed in a folder named usr in the root directory of the drive. If the usr folder already exists, any file it contains that has the same name as a file being copied will be overwritten.
In remote operation, files can only be copied from internal memory to the USB device or from USB to internal memory. If you wish to copy to the same memory device or copy specific files and folders, use the instrument front panel.
The Copy command will not execute if no USB device is plugged into the instrument. Use the :SYSTem:MSIS? USB query to check the ready state of the USB drive before copying files.
Note 
Exercise caution before copying. Large files or a great number of files may take a long time to copy. The instrument will not respond to user input while files are being transferred.

NA (no query)

Copy to Destination
:MMEMory:MSIS:DESTination
Description
Sets the destination location for files copied with the :MMEMory:MSIS:COPY command. If USB is the destination, files and folders will be copied to a directory named usr at the root level of the USB device. If the usr folder currently exists, the COPY command will overwrite any file that has the same name as a copied file.
The Destination command also sets the current save location. For example, selecting the USB Flash drive as the destination will set the instrument’s internal memory as the current save location, and vice-versa.
The destination location specified by SCPI command applies to remote operation. It is independent of and can be different from the destination selected using the instrument front panel. The query form of this command returns the destination location setting for remote operation, not the front panel setting.
This command is ineffective if the specified destination is not available, such as having no USB device plugged into the USB port. Use the :SYSTem:MSIS? USB query to check the ready state of the USB drive.
